Answer:

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules

Explanation:

DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.

In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.
